The mixture which shows positive deviation from Raoult's law is

Which one of the following graphs accurately represents the plot of partial pressure of $CS_{2}$ vs its mole fraction in a mixture of acetone and $CS_{2}$ at constant temperature?

At $T \ K$,two liquids $A$ and $B$ form an ideal solution. The vapour pressures of pure liquids $A$ and $B$ at that temperature are $400 \ mm \ Hg$ and $600 \ mm \ Hg$ respectively. If the mole fraction of liquid $B$ is $0.3$ in the mixture,the mole fractions of $A$ and $B$ in the vapour phase respectively are

At $88\,^oC$,the vapor pressure of benzene is $900 \, \text{torr}$ and that of toluene is $360 \, \text{torr}$. What is the mole fraction of benzene in the mixture with toluene that will boil at $88\,^oC$ and $1 \, \text{atm}$ pressure,assuming it forms an ideal solution?

Two compounds form an ideal solution at room temperature. Which of the following are correct for this ideal solution?
$(A)$ $\Delta G_{mix} < 0$
$(B)$ $\Delta S_{mix} > 0$
$(C)$ $\Delta V_{mix} = 0$
$(D)$ $\Delta_{mix} H = 0$

Raoult's law is obeyed by each constituent of a binary liquid solution when
